I have one particular Windows 2003 VM machine on on my network which keeps dropping off the network. When it drops off RDP or Ping test does not respond and the only way to bring it back online is by disabling and re-anabling network adapter on the guest edit virtual machine settings option. The server is Symantec AV installed with Endpoint Network Protection enabled.
The ethernet card is setup as E1000. Your help will be much appreciated.
Welcome to the communites
Could you please monitor the network utilistaion of that server ?
If that is not cause then most probably please check physical cable .
I dont think endpoint creating any problem ,if so then it will create for ever .
